The sintered bronze bushings are impregnated with Elisha Technologies EDC 1270 EPL, and the void space within the sleeve is filled with EDC 1270 EPL grease. MACHALT (ECP-526) also replaces the self-lubricated bushings previously installed by MACHALT 167-31004 (ECP-444) on quick-acting weather doors.

The wear pads are made from composite material that has been tested (dogged/undogged) more than 1,300k cycles at the NSWCCD-SSES Philadelphia test site. When the wear pad is expended a new dog assembly (complete with wear pad) can be easily installed by Ships Force personnel.
